Technology Gravity Could Trap Alien Civilizations on Super-Earths

The Eagles defeated the Falcons last season in the playoffs, setting Philadelphia up to face the Vikings in the NFC Championship.The reigning Super Bowl champs will play Atlanta on a Thursday, marking the first game of the season. Kickoff is reportedly scheduled at 8:20 p.m. ET.

In fact, any civilizations that are living on massive planets may end up essentially trapped by gravity, suggests a paper posted recently on the pre-print site arxiv.org. That's because stronger gravity requires stronger—and pricier—rockets to overcome.

"On more massive planets, spaceflight would be exponentially more expensive," author Michael Hippke, an independent researcher based in Germany, told Space.com. "Such civilizations would not have satellite TV, a moon mission or a Hubble Space Telescope."

Humans Have Caused Mammals to Shrink

A new study found the average size of mammals has decreased over the last 100,000 years because of human activity.The size of the average mammal has been shrinking for more than 100,000 years – and it's all because of humans.

Humans have been spacefaring beings for less than a century, and there's a good reason for that: rockets are a challenging technology. You need a lot of speed to escape Earth's gravity and reach orbit—about 25,000 miles per hour—and getting all that speed means burning quite a lot of powerful fuel.

But Hippke wondered what would happen when gravity got stronger, as it would on more massive planets that are still rocky worlds, dubbed "super-Earths," where the speed needed to escape gravity could be more than twice as fast.

His calculations suggest that on planets up to about 10 times Earth's mass, extraterrestrial spacefarers could make do with rockets powered by chemical fuels, like ours.

Of course, the heavier the thing any hypothetical aliens wanted to put into orbit, the less practical the endeavor would become. To lift something like a crewed Apollo mission, Hippke calculated the inhabitants of a world 10 times heavier than Earth would need a pile of rocket fuel the same mass as the largest of the Great Pyramids, which he dubs "probably a realistic limit for chemical rockets."

There is one alternative for any gravity-bound extraterrestrials who dream of touching the stars: developing a more powerful source of speed. Specifically, Hippke suggests nuclear-powered rockets.
